    * Frontend envs: [https://github.com/blockscout/frontend/blob/main/docs/ENVS.md](https://github.com/blockscout/frontend/blob/main/docs/ENVS.md)
    * Backend envs: [https://github.com/blockscout/blockscout/blob/master/docker-compose/envs/common-blockscout.env](https://github.com/blockscout/blockscout/blob/master/docker-compose/envs/common-blockscout.env)

  <Accordion title="How do I connect the frontend to the backend?">
    This is done through the [proxy setup](/setup/deployment/frontend-migration/proxy-setup). Ensure you've added the `API_V2_ENABLED='true'` in your blockscout instance.
  </Accordion>

  <Accordion title="Do the frontend and backend need to be under the same domain?">
    Yes. Be sure to proxy all /api, /socket requests to the backend application and all other requests to the frontend. More info on the [proxy setup](/setup/deployment/frontend-migration/proxy-setup) page.

  <Accordion title="What are the variable settings for a Polygon Edge client?">
    Be sure to set the following envs when setting up a Polygon Edge instance:

    * `ETHEREUM_JSONRPC_VARIANT=geth`
    * `INDEXER_INTERNAL_TRANSACTIONS_TRACER_TYPE=polygon_edge`

  <Accordion title="Blockscout API/indexer is using 100% CPU, what should I do?">
    You should allocate more computing resources/cores to the instance.
  </Accordion>

  <Accordion title="What should I set the proxy\_pass variable to?">
    Typically you should set to [http://youripaddress:your\_port\_number](http://youripaddress:8153/;). Blockscout may not work if you set to [http://0.0.0.0:](http://0.0.0.0:8153/;)your\_port\_number
